FOUNTAIN-PEN.

SPECIFICATION forming part of' Letters Patent N0. 792,988, dated June 20, 1905.

Application filed October 8, 1904:. Serial No. 227,670.

.To all whom t may concern:

Be it known that I, SAMUEL H. Honens, a citizen of' the United States. residing' at South Glens Falls,in the county of Saratoga and State of New York, have invented new and useful Improvements in Fountain-Pens, of which the following is a specification.

This invention relates to fountain-pens of the kind which contain an infiatable sack for use in refilling or cleaning the same.

The objects of the invention are to improve and simplify the construction of such devices; furthermore, to increase their efiiciency in operation.

With the foregoing and other minor objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed as a practical embodiment thereof.

In the accompanying drawings, forming part of this specification, Figure 1 is a longitudinal central section of a pen constructed in accordance with the invention, showing the sack defiated. Fig. 2 is a similar section showing the sack inflated. Fig. 3 is a transverse section on the line 3 3 of Fig. 2. Fig. 4 is a side elevation of the combined connector and mouthpiece. Fig. 5 is a side elevation, partly in section, of the shield adapted to be placed over the mouthpiece.

Like reference -numerals indicate corre sponding parts in the different views.

The numeral 1 indicates the barrel of a fountain-pen, and 2 the nib thereof. These parts may be of any suitable form and construction.

The barrel 1 is formed at the end thereof opposite the nib 2 with a threaded bore 3, into which is fitted a combined mouthpiece and connector 4, the threads 5 of which are of greater length than the threads of the bore 3, so that when said combined connector and mouthpiece is screwed into the threaded bore of the barrel 1 a portion of the threads 5 will extend outwardly beyond the end of the barrel. The end of the mouthpiece 4 within the barrel 1 is formed with a tubular extension 6, to which is connected in any suitable air-tight manner the small end of an inflatable sack 7 which is disposed within the barrel 1. The combined connector and mouthpiece 4 is formed at one end with a cone-shaped valve-seat 8, with which cooperates acone-shaped valve 9. The taper of the valve9 is more acute than the taper of the valve-seat 8, whereby said valve contacts with the valve-seat only at the portions thereof immediatelyv surrounding the entrance of the bore 10, which extends longitudinally through the mouthpiece 4 and terminates in an enlarged bore 11. Connected with the valve 9 and extending through the bore 10 is a valve-stem 12, which is formed with lateral extensions or arms 13, disposed in the enlarged bore 11 in such manner as to limit the extent to which the valve 9 can move away from its seat 10. Screwed upon the portion of the threads 5 of the mouthpiece which projects beyond theV threaded bore of the barrel 1 is a shield 14. The ordinary' cap 15, which is intended to cover the nib 2 when the pen is not in use, is adapted to be fitted over the shield 14, as shown in the drawings.

Constructed as above described the manner of using the improved pen is as follows: l/Vhen the pen becomes empty and it is desired to refill the same, the cap l5 and shield 14 are removed from the' combined connector and mouthpiece 4. The lips are applied to the mouthpiece 4, and the sack 7 is distended, as shown in Fig. 2, in order to force the air out of the barrel 1. After the air has been forced from the barrel 1 the nib 2 is submerged in ink, and by applying suction to the mouthpiece 4 the sack 7 is deflated in such manner as to cause the barrel 1 to become filled with ink.

By employing a valve such as 9, with a more acute taper than its seat, said valve is adapted to be moved away from its seat by the tongue or teeth when it is desired to in- .fiate the sack 7 Changes in the precise embodiment of invention illustrated and described may be made within the scope of the following claims without departing from the spirit of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed is- 1. In a fountain-pen, the combination with a barrel having an infiatable sack therein, of a combined connector and mouthpiece connect- IOO ed with said barrel and with said sack, and a removable shield fitted in an air-tight manner over said connector and mouthpiece.

2. In a fountain-pen, the combination With a barrel having an iniatable sack therein, of a combined connector and mouthpiece connected With said barrel and with said sack, and having a valve therein, and a shield adapted to be itted oversaid combined connector and mouthpiece in an air-tight manner to reinforce and protect said Valve.

3. In a fountain-pen, the combination with a barrel having a threaded bore at one end, a nib at the other end, and an iniiatable sack therein, of a combined connector and mouthpiece having a conical valve-seat, a longitudinal bore extending' therefrom and opening into an enlarged bore, a tubular extension, said connector and mouthpiece having screw-threads of greater length than the threaded bore of said barrel, said combined connector and mouthpiece being fitted into the threaded bore of the barrel and having its tubular extension connected with said sack, a cone-shaped valve having a more acute taper than the taper of said cone-shaped valve-Seat, a stem connected with said Valve and extending th rough the longitudinal bore of said mouthpiece, enlarged lateral extensions on said stem, located in said enlarged bore, a shield screwed upon the threads of said com bined connector and mouthpiece, and a cap fitted over saidshield.

In testimony whereof IaiX my signature in presence of two Witnesses.
